Rotary Piston reloaded.

The invention relates to a rotary machine with eccentric piston, that can be a pump, compressor, pneumatic motor, hydraulic motor or internal combustion engine. According to the invention, the rotary machine has a cylindrical piston (1) mounted in a cylindrical housing (2) tangent to the inner cylindrical wall of the cylindrical housing (2), the cylindrical piston (1) being provided with a sealing piece (3), wherein a rotary blade (4) can glide, said blade being integral with a driving shaft (5 ) whose rotation axis concides with the axis of the cylindrical housing (2), the rotary blade (4) being in permanent contact with the inner cylindrical wall of the cylindrical housing (2); between the rotation axis of the cylindrical piston (1) and the axis of the cylindrical housing (2) there is provided an eccentricity (e).

Why?: what losses are there in a conventional reciprocating or rotary pump that are reduced in this design and why is this the case? And what fluids would this pump be good at pumping into the reservoir.

but it is greatly improved. The pallet is tied to the spindle and the pallet does not need to rub the stator.

But.... we can use an assembly of a hydraulic motor with a hydraulic pump.
We supply with water to the hydraulic engine, which receives water at the pressure depending on the depth of the drill well.
With the mechanical work done by the hydraulic motor we operate the pump!

My son has a book, Machines, that was written in 1964. It has pages that show schematics of popular machines (toasters, refrigerators etc.) In the drawing of the refrigerator compressor, the same structure is shown.

This seems to be your invention. Tell me, is the patent document you linked to a granted patent or just a published patent application? It is normal for patent offices to publish the application, so that interested parties can raise any objections before it is granted. The prior art search sometimes goes on after publication. To be honest I would be surprised if a patent is granted, as it looks to me as if it has been anticipated by existing designs.
